A tomato harvesting robot to work in large scale greenhouse has been studied by our research group. This robot harvested a fruit by bending its stem instead of by cutting the stem. Some fruits without calyx were harvested by the robot, although tomato fruit with calyx for fresh market are sold in Japan. To solve this problem, in this study, a harvesting end-effector was improved to harvest a fruit with calyx.

Large scale Dutch style greenhouses for tomato production have been introduced in many countries recently. Automation systems for many kinds of operations in them are required for improving the conditions of labor shortage, monotonous works, sterilization operation, working efficiency on seedling production, spraying and harvesting operations. In this research, hormone spray and harvesting operations were focused, and machine vision systems and an end-effector were investigated. Because tomato flower petals have higher reflectance in UV region than in visible region, a UV camera and a color camera images were compared. Although end-effectors to harvest individual tomato fruits were already reported so far, an end-effector to harvest a whole fruit cluster was developed and experimented.

In this study, an end-effector to harvest whole tomato cluster including 4 to 6 fruits was designed and was manufactured as a trial. Before designing the end-effector, physical properties and dynamic properties of tomato plant were measured The end-effector made as a prototype mainly consisted of upper fingers, lower fingers, and a pushing device. Peduncle graspers and peduncle cutters were attached to the upper fingers by use of springs and cutters. The upper fingers moved upward and downward by a ball screw, while the peduncle graspers slid and grasped the peduncle with spring forces, when the upper finger moved downward Both upper and lower fingers opened and closed through push pull cables driven by solenoid actuators. A pushing device was attached to this end-effector to prevent fruit cluster swinging during transporting the fruit cluster to a tray from tomato plant.
